Density: ρ = m/v Specific gravity: ratio of one density to density of water P = F/A P 2 – P 1 = ρ g(y 2 – y 1 ) P = P 0 + ρ gh Pascal’s Law: pressure applied to a fluid is transmitted undiminished to every portion of the fluid & walls of vessel F 2 = (A 2 /A 1 )F 1 Gauge pressure: amount above atmospheric pressure: p – p atm = ρ gh Absolute pressure: atm pressure + gauge pressure Archimedes Principle: when body is completely or partially immersed in a fluid, the fluid exerts an upward force on the body equal to the weight of the displaced fluid Buoyant force: weight of displaced fluid Ideal fluid: incompressible Viscosity: internal friction A 1 V 1 = A 2 V 2 dv/dt = AV= volume flow rate Mass flow rate = ρ (dv/dt) Bernoulli: P + ρ gy + ½ ρ v 2 = constant P 1 + ρ gy 1 + ½ ρ v 1 2 = P 2 + ρ gh + ½ ρ v 2 2 Transverse Waves: displacement of medium perpendicular to direction of travel Longitudinal Waves: displacement of medium in same direction as direction of travel Wave Speed:
